The goal is to prove that patients participating in one of two lifestyle interventions, a more intense health promotion intervention or a less intense text-message program, will report improved physical parameters: BMI, BP, metabolic parameters (fasting serum glucose, serum cholesterol), health-related quality of life, recovery of EF and urinary continence (the latter three as reported by questionnaires) compared to patients who are given standard advice prior to radical prostatectomy.
